Rohde & Schwarz Hameg HM6050-2 LISN Teardown

(1/1)

vzoole:
I just changed my homemade LISN and I thought it would be a good idea to look inside of the new one.

Hello,

our Hameg HM6050-2 LISN is damage, and I need the references of the components in the picture below, if you can send me the reference of that components Thanks

Sincerly 

vzoole:
It is glued to the PCB so I wouldn't desolder it for measure if it isn't necessary. But my best guess is two 100 Ohm paralel.

Hydron:
That's pretty much the best possible 1% tolerance value - no ambiguity even if you can't tell which band is the tolerance one :)

Jar:
Hi.

How is it in work?

I got issue with mine. measure on L with limiter off got 10dBuV more noise in range below 300KNz compared with N. No DUT connected.

if I swap power plug of HM6050 180 degree. nothing changes(I expected to have noise moved to N). That makes me thing it comes from LISN it self(
